Typhoon Bavi Causes Widespread Work and School Closures? Clear Morning Skies, But Experts Reveal Timing of Rain and Wind Across Regions: Heavy Rain and Strong Winds Arrive at This Hour

The Central Weather Bureau officially issued a land-based typhoon warning for this year's Typhoon Bavi early on the 10th. The initial land warning zone includes New Taipei City, Yilan County, and Hualien County, with further expansion expected as the typhoon approaches Taiwan. The weather-focused social media page 'Weather Instant Forecast' noted that although Typhoon Bavi previously reached peak intensity during its development, it has slightly weakened to a moderate typhoon due to disruption from vertical wind shear in the atmosphere and internal structural reorganization.

Despite the slight downgrade in intensity, Typhoon Bavi still possesses an extremely broad wind circulation, meaning residents across Taiwan will experience significant wind and rain over the coming days.

When will the typhoon's path and most severe impacts occur?

According to the latest observations and track forecasts from the Central Weather Bureau, Typhoon Bavi continues moving in a northwesterly direction. Slight adjustments in its forward speed have delayed the timing of the storm's outer bands making landfall compared to earlier predictions, thereby extending the overall duration of impact on Taiwan.

Meteorological experts predict that the typhoon's wind field will not begin to affect Taiwan until late on the 10th. The most intense period, with concentrated wind and rain, will begin in the afternoon of the 10th and persist through the morning of the 12th. The 'Weather Instant Forecast' page also highlighted atmospheric trends, emphasizing that as widespread rain and wind move in, weather conditions across Taiwan will follow a 'worsening toward the north' pattern.

Which counties and cities have announced work and school suspensions, and how is the timing of rain and wind distributed?

In response to the threat of wind and rain brought by the typhoon, local governments across Taiwan have made assessments and announcements regarding work and school suspensions. Currently, Miaoli County, Hsinchu City, Hsinchu County, Taoyuan City, New Taipei City, Taipei City, Keelung City, Yilan County, Hualien County, and Lienchiang County have all announced full suspensions. Additionally, Taichung City and Nantou County have followed suit, announcing work and school suspensions starting at 6:00 PM on the 10th.

Regarding the timing of wind and rain across regions, northern Taiwan and Yilan will be the first to feel the effects of the outer circulation, with the strongest wind and rain occurring from the afternoon of the 10th through all of the 11th. The offshore Lienchiang (Matsu) area is expected to experience the strongest conditions from the morning of the 11th through the morning of the 12th. Wind and rain in central lowlands, Penghu, and Kinmen are expected to intensify from the afternoon of the 10th and continue into the early hours of the 12th—this is why Taichung and Nantou have extended their disaster preparedness timelines. As for southern lowlands and Hualien, the most noticeable impacts will occur from the afternoon of the 10th through the early hours of the 11th.

Which areas need special attention for strong winds and heavy rainfall?

In terms of wind and rain distribution, due to Typhoon Bavi's exceptionally broad wind field, the 'Weather Instant Forecast' page warns that northern regions, Yilan, western coastal areas, and all high-elevation mountainous areas across Taiwan should be on high alert for damaging strong winds during the typhoon's passage. Regarding rainfall, northern and Yilan areas—being closest to the typhoon's center—will experience intense rainfall both in lowlands and mountainous regions, requiring vigilance against flooding and water accumulation.

Although rainfall in southern lowlands and Hualien is expected to ease by the early hours of the 11th, significant orographic rainfall will occur in central and southern mountainous areas due to the windward slope effect, with rain continuing through the 12th before gradually subsiding.

Forecasts from the Central Weather Bureau indicate that Friday and Saturday will see the strongest wind and rain from this typhoon, with considerable cumulative rainfall. Widespread rain will not begin to ease until after Sunday (the 12th). Even in areas not meeting full suspension criteria, noticeable strong winds are expected during the evening commute on the 10th, prompting all residents to remain highly vigilant when traveling.
